Technical Field

[0001] The utility model relates to the technical field of connecting shaft processing, in particular to a connecting shaft pin hole processing device. Background Art

[0002] When processing the pin hole of the connecting shaft, after the hole is opened by machine, it needs to be polished to remove burrs near the hole.

[0003] The most traditional deburring process is manual deburring, where workers use files, sandpaper and other tools to grind and deburr parts. The pin hole of the connecting shaft is flat, so manual deburring can be used. Manual deburring eliminates the need for equipment, so the cost is relatively low. However, the manual operation process is long and inconvenient.

[0004] Therefore, it is necessary to improve the traditional manual deburring of pin holes, that is, a processing device that can assist manual deburring of pin holes is needed to reduce the burden on workers. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A connecting shaft pin hole processing device comprises a base 1, a vertical hole 2 is formed on the base 1, a convex block 3 is fixed on the base 1 by bolts, a circular ring 4 is rotatably connected to the base 1, a bent rod 5 is fixedly connected to the circular ring 4, a screw hole 8 is formed on the bent rod 5, a screw rod 9 is threadedly connected to the screw hole 8, a grinding seat 10 is fixedly connected to the end of the screw rod 9 by bolts, and a limiter for limiting the position of the grinding seat 10 is provided on the bent rod 5. Rotating the screw rod 9 can cause the grinding seat 10 to move in the vertical direction until the grinding seat 10 contacts the plane of the connecting shaft, which is convenient for subsequent grinding operations.

[0025] Specifically, Figure 4 As shown, the limiting member includes a round rod 6 fixedly connected to the bent rod 5, and the round rod 6 is slidably connected to the through hole 13 provided on the slider 12. The slider 12 is provided with a transverse hole 14, and a slide rod 15 is slidably connected to the transverse hole 14. A clamping block 17 is fixedly connected to the end of the slide rod 15, and a clamping groove 11 adapted to the clamping block 17 is provided on the grinding seat 10. A handle 16 is fixedly connected to the end of the slide rod 15. After the clamping block 17 is inserted into the clamping groove 11 of the grinding seat 10, it can limit the grinding seat 10, so that the grinding seat 10 cannot rotate even if it is subjected to external force. The grinding seat 10 can rotate together with the rotation of the bent rod 5, and the grinding seat 10 can grind and deburr the plane of the connecting shaft.

[0026] Specifically, Figure 3 As shown, a spring 1 7 is sleeved on the round rod 6, one end of the spring 1 7 is fixedly connected to the bend of the bent rod 5, and the other end is fixedly connected to the bottom of the slider 12. A spring 2 18 is sleeved on the slide bar 15, one end of the spring 2 18 is fixedly connected to the side wall of the slider 12, and the other end is fixedly connected to the side wall of the block 17.

[0027] Specifically, Figure 3 As shown, the side wall of the slider 12 is slidably connected to the bend of the bent rod 5, and the elastic force of the spring 1 7 pushes the slider 12 to move upward. Therefore, after the block 17 is separated from the slot 11, the slider 12 can move upward and return to its original position by itself.

[0028] In summary, the pipe of the connecting shaft provided in this embodiment is inserted into the vertical hole 2, and the pin hole of the connecting shaft is sleeved on the protrusion 3. Pull the handle 16 to make the clamping block 17 away from the screw rod 9, and then the screw rod 9 can be rotated until the clamping groove 11 on the grinding seat 10 is aligned with the clamping block 17, and then the pulling force on the handle 16 can be released. Under the elastic force of the spring 18, the clamping block 17 is inserted into the clamping groove 11, and then the screw rod 9 is continuously rotated, so that the grinding seat 10 contacts the plane of the connecting shaft, and the bending rod 5 is rotated, so that the grinding seat 10 rotates with the bending rod 5, thereby grinding the plane pin hole of the connecting shaft to remove burrs.
